SliverAnimatedList class Null safety

A sliver that animates items when they are inserted or removed.

This widget's SliverAnimatedListState can be used to dynamically insert or remove items. To refer to the SliverAnimatedListState either provide a GlobalKey or use the static SliverAnimatedList.of method from an item's input callback.

This sample application uses a SliverAnimatedList to create an animated effect when items are removed or added to the list.

To create a local project with this code sample, run:
flutter create --sample=widgets.SliverAnimatedList.1 mysample
